The Baja 5B is huge, powerful and ready for action, and with the amazing D-Box 2 you'll be in full control of this massive 10kg (22 lb) beast anywhere you go! With a mighty 23cc 2-stroke engine powering the huge, rear-wheel drive Baja 5B buggy, you can easily hit speeds over 30mph!

The Baja 5B is fitted with externally adjustable VVC/HD shock absorbers on all four corners and a super-tough, high torque large scale metal gear steering servo. It's got our ultra-reliable 2.4GHz radio system, big battery pack powering the steering and throttle servos plus a battery charger, so you're ready for instant Baja action! The radio box is also fitted with the #105409 D-Box 2 Adjustable Stability Control System that will give you total confidence at any speed, on any kind of terrain you're driving on. It's perfect for driving on slippery surfaces with a powerful rear-wheel drive car like the Baja 5B, because you can change its sensitivity to make the car more stable as it's cornering…or help it kick out the rear end for awesome drifting action!

The Baja 5B also features an extra-thick monocoque aluminum chassis, 700cc fuel tank for up to 45 minutes of driving before refueling, painted body in an all-new design and pre-mounted wheels and tires so you are ready to rock! The Baja 5B has the huge size and amazing looks that will amaze your friends, and now it's more controllable than ever, thanks to the awesome D-Box 2!

The D-BOX 2 is your Secret Weapon for perfectly controlled driving!

The D-Box 2 is a fantastic electronic aid for drivers of all skill levels, in any kind of RC car, on any kind of driving surface. Whether you take your Baja 5B out on grass, loose dirt, mud or ultra-grippy clay, you will get perfect control thanks to the magic of HPI Drift Assist technology! The super-small D-BOX 2 simply connects between the receiver and steering servo for an amazing difference in your driving performance!

The D-BOX 2 has an amazing feature that improves response over other driving assistance systems when the gyro sensitivity is increased (Patented steering operation priority system) using the provided Mode switches. This new priority system allows the steering inputs from the transmitter to have priority over the gyro. While the D-BOX 2 is perfect for all types of vehicles, this gyro correction is seen the most when used in high-powered off-road cars: increasing the throttle will not spin the car out, even in slippery conditions! The D-BOX 2 will also prevent sliding in sudden braking or steering.

Exclusive Sensitivity Mode Switch

The HPI D-BOX 2 allows you to set 4 sensitivity modes using 2 switches. Mode 0 has the characteristics of the original D-BOX, with gyro compensation present from the steering action provided by your radio signal. You can get more steering control and less gyro compensation as you change the modes up to Modes 1, 2 and 3 - if you want earlier steering response through the transmitter and less from the gyro, simply change the mode to a higher number. Test drive the different modes to find the optimal driving mode for your preference!

The D-Box 2 will help you drive smoother, faster and with more control - and it's fitted in the Baja 5B right out of the box!

Featuring the New TF-45 2.4GHz Radio System!

The Baja 5B now also features the new TF-45 radio system - a 3-channel, 2.4GHz radio that has all the most-desired features experienced RC drivers crave. Among its many features are Frequency-Hopping Spread Spectrum (FHSS) digital 2.4GHz radio technology, end-point adjustments and electronic failsafe protection, plus dual-rate, trim and reversing functions. It's also lightweight and comfortable thanks to its drop-down steering wheel, changeable grip size and padded steering wheel.

Element-Proof Protection

The Baja 5B features protection for its electronics and it's ready to tackle wet conditions like mud, rain and snow! The 2.4GHz receiver is safely stored in an element-proof receiver box, protecting it in wet conditions to ensure glitch-free operation. A large rubber plug provides easy access to the receiver battery. To remove the radio box when you're cleaning the car, just remove a few clips - no tools necessary! Please note: the electronics are not designed for submerged operation. Be sure to rinse off any dirt or salt water with clean water immediately after driving. Check the receiver box to make sure no water is inside and let dry fully before driving again.

Extra-Thick Aluminum Chassis!

The Baja 5B uses a unique chassis design that has inspired imitators and pretenders that are still trying to dethrone the Baja from the top of the heap. The extra-thick Baja monocoque aluminum chassis is formed from strong 6061 aircraft aluminum for light weight and strength, then bent into shape with computer precision to make it into an extra-rigid and super-strong platform for the engine, suspension and all other components of the Baja.

Huge 23cc 2-Stroke Engine

The engine fitted in the Baja 5B features extra power over earlier Baja engines, and when combined with the High Flow Muffler and 8000 RPM clutch, you'll experience extra-fast top speeds and jaw-dropping acceleration for more fun! The High Flow Muffler from the Baja 5T is a much larger capacity design than the old standard muffler, and is tuned to give you more horsepower on the track. It sounds fantastic, too! When the Baja 5B is ripping past you, you will know it!

8,000 RPM Clutch

Formerly an option part, the high performance 8000 RPM Clutch from the Baja SS and 5T is used to give the Baja 5B more punch, or acceleration, off the line. Lightweight clutch shoes and a strong heavy-duty spring are the integral parts of this unit, and you will definitely feel the power out of the turns!

45 Minutes of Driving Time per Tank

The fuel tank holds 700cc of pre-mixed 2-stroke fuel, using normal pump gasoline and easily available 2-stroke engine oil. This amount of fuel will give you run times of 45 minutes or more and the handy flexible 'clunk' inside allows the engine to keep running even if the car is upside down after a crash. Imagine that - 45 minutes of fun before you have to stop to refuel! Welcome to large scale RC!

Long-Stroke VVC/HD Racing Shocks

These are the same top-quality shock dampers that are equipped on the racing-level Baja SS and bigger (and heavier) Baja 5T, and are also standard parts for the Baja 5B. These are race-quality, endurance tested, oil-filled, externally adjustable coilover shocks for fantastic performance and heavy-duty track action! Extra-thick shock shafts provide security from crashes, threaded shock bodies allow instant ride height changes, and the externally adjustable piston design is tailor-made for fast trackside tuning.

Durable Off-Road Beadlock Tires

To allow the Baja buggies to go just about anywhere, we fit tires that are ideally suited for nearly all off-road conditions. The unique beadlock off-road tires combine to provide the perfect amount of traction and control on dirt, gravel and grass surfaces. The Dirt Buster S Compound rear tires use a versatile square pin design that easily sheds excess mud and grass, giving you the grip you need for massive top speed runs, while the Dirt Buster rib tires provide the direction and steering necessary for pinpoint accuracy on the track.

Extra-Strong Suspension Parts

HPI has always been known for its extremely rugged cars and trucks, starting with our earliest touring cars and carrying on with monster trucks and large-scale machines. The Baja 5B uses the exact same suspension components as the Baja SS and 5T, so you know you've got a quality buggy in your hands. Durable plastic compounds and smart design combine to make the Baja 5B super rugged on any kind of terrain, so you can bash, race and play with your friends for hours before needing to think about maintenance or repair.

Front and Rear Protective Skid Plates

Complementing the durable suspension components and protecting the chassis from big crashes and mishaps, the Baja 5B is protected at the front and rear by thick skid plates. These allow the Baja to slide over bigger obstacles and also help prevent major damage to the chassis. The rear skid plate can be quickly removed without tools to access the engine mount screws for fast maintenance.

Powerful Vented Disc Brake

To bring something the size and speed of the Baja 5B buggy to a safe and controlled stop, the brakes need to be extra-strong, reliable and foolproof. This is why we use two steel plates for brake discs, both of which are drilled for lightness. To keep the discs cool under pressure, a fan-shaped spacer is used blast rotating air through the vent holes drilled in each disc.

Protective CVD Boots

Helping to keep the Baja 5B running at top speed for hours at a time, the driveshafts are fitted with extra-flexible rubber boots at each end. The boots keep mud, dirt and grass away from the driveshaft and axle joints, and also keep lubricating grease in place around the joints.
